Abstract

L'invention concerne l'utilisation comme luminophore dans des systèmes à plasma d'un composé à base d'un phosphate d'yttrium, de gadolinium ou de lutécium, dopé par au moins une terre rare choisie dans le groupe comprenant le terbium, le praséodyme et le cérium. Ce luminophore est absorbant dans le domaine d'émission du plasma et émet dans le domaine du visible avec un bon rendement et une couleur appropriée de manière à être particulièrement utile dans de nouvelles techniques de visualisation et d'éclairage tels que, par exemple, les écrans de télévision plats.The invention relates to the use as a phosphor in plasma systems of a compound based on an yttrium, gadolinium or lutetium phosphate, doped with at least one rare earth chosen from the group comprising terbium, praseodymium and cerium. This phosphor is absorbent in the plasma emission range and emits in the visible range with good efficiency and an appropriate color so as to be particularly useful in new visualization and lighting techniques such as, for example, flat TV screens.
